Members of the NAI UCLA team led by Ed Young are using high-precision analysis of tiny grains in meteorites to probe the earliest history of the solar nebula. The age of the solar system is set at ...

A new study uses carbon isotope science to show that marked tusks in a seized ivory shipment were more than 30 years old and likely had found their way from a guarded government stockpile into the ...

Oxygen isotopes data enable researchers to look far back into the geologic past and reconstruct the climate of the past. In doing so, they consider several factors such as ocean temperature and ice ...

In arid northern Kuwait, scientists lower a sampling tube deep into a dry well to reach the shallow pool of groundwater at its bottom. The water, which has been hidden underground for thousands of ...

Besides honey, stable isotope techniques are also used to verify the authenticity and origin of products such as edible bird’s nests, coffee, beef, rice, Harumanis mangoes, and cocoa beans, and can ...

A common use of stable isotope analysis in mammalogy is to make inferences about diet from isotope values (typically δ¹³ C and δ¹⁵ N) measured in tissues and food sources of a consumer. Mathematical ...
